    • When connecting a probe to the instrument for the first time, perform phase correction of the probe as described in section 3.5, “Compensating the Probe (Phase Correction)” in the DL1620/DL1640/DL1640L User’s Manual IM 701610-01E . Failure to do so may result in unstable gain across different frequencies, thereby preventing correct measurement.

  • Page 44: Chapter 2 Spi Bus Signal Analysis Function

    MSB First Note • On the DL1640/DL1640L, the clock signal is input to CH1; the data input signal (Data1 and Data2) to CH2 and CH3; and the chip select signal (CS) to CH4. • Data is transmitted in units of bytes (8 bits) by synchronizing to the clock signal.

  • Page 45: Connecting The Probe

    CH4: Chip select signal (CS) * CH2 and CH3 can be connected to either the data input signal or the data output signal. The DL1640/DL1640L handles the data of the signal connected to CH2 and CH3 as Data1 and Data2, respectively.
